BMW, Daimler, Volkswagen and dynaCERT - the cleanest diesel ever
In a recent vehicle test, experts examined the BMW 520d, Mercedes-Benz GLE 350 and VW Golf 2.0 TDI models in city traffic, on country roads and autobahns. The magazine 'Auto, Motor und Sport' and the British testing specialist Emissions Analytics have tested the emission of nitrogen oxide (NOx) in road traffic under real conditions and the results are surprisingly good. The advantages of electric mobility are fading.

New exhaust emission standard Euro 6d-Temp
When the diesel scandal became known in 2015, tests of vehicles in the laboratory under optimized conditions were the required common practice for car manufacturers. In road traffic and under real conditions, however, emissions of up to 1,000 mg NOx per kilometer were still measured in Euro 6 diesel engines. Since September 2019, even stricter rules have been in force for new diesel engines with Euro 6d-Temp, because since then, vehicles may only emit 168 mg NOx per kilometer.
Diesel engines almost without NOx emissions
The engineers of the German carmakers were able to shine with their results when testing the three vehicles BMW 520d, Mercedes-Benz GLE 350 and VW Golf 2.0 TDI in road traffic. According to the report, the BMW 520d measured only 29 mg NOx per kilometre. The Golf model of the Wolfsburg car manufacturer only measured 20 mg NOx. The Mercedes SUV GLE achieved the best result in hybrid operation with 16 mg NOx per kilometer. In pure diesel mode, the vehicle with 306 hp and 2.0 liters of engine capacity achieved 22 mg NOx per kilometer, according to the testers. The measurement also showed that the particulate emissions in terms of the number of particles and their mass were far below the limit requirements for the three vehicles.
Advantages of electric cars are fading
These results give hope for the German automotive industry, whose strength is the development of combustion engines. These new results should send a signal to politics and industry. Many jobs in Germany depend on the combustion engine. The change to battery cars is progressing only slowly and with subsidies from tax payers' money.
It remains to be seen whether the current Corona Crisis will spur interest in electric cars and expensive experiments. There is currently a lack of attractive models and the necessary infrastructure to charge the batteries. Furthermore, the origin of the charging current often distorts the ecological balance of electric cars.
dynaCERT makes diesel green
The advantage of diesel engines is the comparatively low fuel consumption. There are currently around one billion diesel engines in use worldwide. In addition to vehicles and heavy equipment, engines of this type are also used in generators, locomotives, trains and ships. A huge market for dynaCERT and the innovative HydraGEN equipment for retrofitting. HydraGEN is a hydrogen technology that can be retrofitted to existing diesel engines of any kind.
The advantage is that fuel consumption can be reduced by up to 20%. Furthermore, the emission of NOx is reduced by up to 88%. A reduction in particulate matter of up to 55% and in CO2 of up to 10% has also been measured. The purchase of HydraGEN usually pays for itself within less than one year. Among the well-known investors of the listed company are the Canadian billionaire Eric Sprott and German logistics expert Dr. Jörg Mosolf.
